A sensing module includes a first coil, a control component coupled to the first coil, and a shielding
component positioned at least on a first side of the first coil. The control component is configured to
drive the first coil to transmit a first emitting electromagnetic signal, and to receive an induction signal
generated from the first coil induced due to a first feedback electromagnetic signal. The shielding
component shields at least a portion of the first emitting electromagnetic signal transmitting toward
a first direction. |
